blockUI 错误“对象不支持此属性或方法”

发布于 2024-10-20 21:53:48 字数 653 浏览 2 评论 0原文

我在 VS2010 中运行它，提交表单时出现错误，显示“Microsoft JScript 运行时错误：对象不支持此属性或方法”。有什么建议吗？

<script type="text/javascript">
function BlockUI() {
    $.blockUI({ message: "<h1>Remote call in progress...</h1>" });
}
</script>

@using (Ajax.BeginForm("Switch", new AjaxOptions()  {
        UpdateTargetId = "Switch" + Model.Id, 
        InsertionMode = InsertionMode.Replace,
        OnSuccess = "",
        OnBegin = "BlockUI()",
        OnComplete = "",
        OnFailure = "alert('Failed to update switch')",
        Confirm = "",
        HttpMethod = "POST",
        LoadingElementId = "",
        Url = ""
    }))

I'm running this from within VS2010 and an error comes up when the form is submitted which says "Microsoft JScript runtime error: Object doesn't support this property or method". Any suggestions?

<script type="text/javascript">
function BlockUI() {
    $.blockUI({ message: "<h1>Remote call in progress...</h1>" });
}
</script>

@using (Ajax.BeginForm("Switch", new AjaxOptions()  {
        UpdateTargetId = "Switch" + Model.Id, 
        InsertionMode = InsertionMode.Replace,
        OnSuccess = "",
        OnBegin = "BlockUI()",
        OnComplete = "",
        OnFailure = "alert('Failed to update switch')",
        Confirm = "",
        HttpMethod = "POST",
        LoadingElementId = "",
        Url = ""
    }))

您应该更改

OnBegin = "BlockUI()",

为

OnBegin = "BlockUI"

根据 MSDN OnBegin 需要：

JavaScript 函数的名称
在页面更新之前调用。

附加的 () 可能会使底层 JavaScript 立即执行该函数，从而导致错误。

类似地，对于 OnFailure：

OnFailure = "function() { alert('Failed to update switch'); }",

此外，您不需要指定未使用的 AjaxOptions 的属性值：

@using (Ajax.BeginForm("Switch", new AjaxOptions()  {
        UpdateTargetId = "Switch" + Model.Id, 
        InsertionMode = InsertionMode.Replace,
        OnBegin = "BlockUI",
        OnFailure = "function() { alert('Failed to update switch'); }",
        HttpMethod = "POST"
    }))

You should change

OnBegin = "BlockUI()",

OnBegin = "BlockUI"

According to MSDN OnBegin takes:

The name of the JavaScript function to
call before the page is updated.

The additional () probably makes the underlying JavaScript execute the function immediately, causing the error.

Similarly, with OnFailure:

OnFailure = "function() { alert('Failed to update switch'); }",

Also, you don't need to specify property values of AjaxOptions that you aren't using:

@using (Ajax.BeginForm("Switch", new AjaxOptions()  {
        UpdateTargetId = "Switch" + Model.Id, 
        InsertionMode = InsertionMode.Replace,
        OnBegin = "BlockUI",
        OnFailure = "function() { alert('Failed to update switch'); }",
        HttpMethod = "POST"
    }))
